Not sure, but I think it is a new ECM. My understanding is warranty is 8 yrs/80K miles. You are certainly okay on the years, how about the miles??? Also, I am of the understanding that anything that can affect emissions has to be warranted for 100K miles. Surely the ECM can "affect emissions", so I would expect it to be covered up to 100K. Talk to a dealer, Toyota claims to have a superior product... let them prove it.
